. Be it known that I, WiLLrAMMILLs, a citizen of. the United States, anda residentof- Elizabeth, county. of'Uiiion, and State ofr New Jersey,-have invented a new and useful Im ro'vein'ent in Means for ConnectinWires to inding-Posts, of which the following is a specification.Heretofore wherever' gas -engines have been used and caused vibration ofthe battery or other electric device used to ignite the mixed ases oftheengine either in launches, automo il, or otherstructures great troublehas been experienced by the disconnection of the conductors ,and thebinding posts, as these vibrations seldom fail to cause the nuts orscrews to lwork-loose.; vFrom this cause thecircuit is broken. Theobject of my invention is to' avoid this trouble wherever it mayoccur-and witho t.

in anyway altering or changing the term nals. This l acc'om lis'h by myinvention, which consists, broa y speaking, in. securing an expansiveand resilientwa'sher to the conductor which washer is adapted to becomon the binding-post when in use and and cause it to make a goodcontact.

For a more particular description of my inventionreference' is to be hadto the accompanying forming a part hereof,

he con uct`or 6 is preferably soldered to the plate 7 and inclosed inpart by the bentover 'armsS of the ,means 5. 'One end of the plate 7 isformed into a disk 9, from the cene ter of which is's'truck the annularflan e 10,

. A peculiar washer 1'1, of rubber or other re silient material, isformed, as shown in Fig. 5,

preferably, with acylindrical exterior and a cylindrical bore 12,somewhat enlarged; asat 12, between shoulders 13 and 14, for reasonshereinafter set forth.

In the structure shown in Fig. 8 the disk 9al is slightly cupped to ivethe washer 1 1 additional resiliency. T e'washer 11 is secured to thedisk 9 in the manner described above by means of the flange 10. Thiswasher 11 is forced over the flange 10, its rim 12b enterl ing theannular extension 12'* of the bore 12,

as indicated in Fig. 4, until the washer 11 is firmly ressed against thedisk/9. The affixture o the was er to the iian e 10 changes itseicterior from a cylindric' to a conical' form. The flan e 10 ressing onthe shoulder 14 of thewas er, t e washer and diskvare firmly heldtogether. The conductor 6 is means of the soldering and the arms S.Between these arms. S the plate is sli htly depressed, as shown in Fig.7, to-better old the conductor.

To' connect the conductor' to the post 2 .by ni im rovedmeans 5, asshown in Fi 1 an 2, t e nut 4 is turned and presses t e disk 9 and thewasher l1 between it and the vnut 3, whereby this plate is securelyheld, .an

electrical contact between the conductor 6 and binding-post 2 madethrough the disk 9 and nut4, and all dan er of a broken circuit orbrokenconnection etweenthe bindingpost and conductor is obviated. Thenut 4 `should preferablybe turned till the shoulder 13 is forced againstthe projection-flange 10,

as akes the best contact and obtains the bes results.

The extension 12 of the bore 1-2 lends expansibility to the washer inaddition to the resiliency of the Amaterial of moved home an compressedgradilally and more readily than if the washer were entirely solidbetween its faces.
